AUTOMOBILE-GATE.

Specification of Letters Eatent.

Patented Mar. 19, 3 .918,

Application filed November 22, 1917. Serial No. 203,410.

To all whom it may concern:

Be it known that 1, WILLIAM H. Zorn, a citizen of the United States,residing at Harrisburg, in the county of Banner and State of Nebraska,have invented a new and useful Automobile-Gate, of which the followingis a specification.

The device formin the subject matter of this application'is a apted tobe employed under conditions which require a normally elevated gate, theconstruction being such that the gate may be pressed downwardly by apassing vehicle, to permit the vehicle to move along its way.

The invention aims to provide novel means for supporting the gateyieldingly, to provide novel mechanism for attaching the raising meansto the gate, to provide novel means for slidably connecting the ends ofthe inclined tracks with the gate, and, generally to improve and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the detail of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the drawings: Fig. 1 shows in vertical section, a device constructedin accordance with the present invention;

Fig. 2 is a top plan wherein the parts'are' omitted and broken away; and

Fig. 3 is a section on the line 3-3 of Fig. 2.

In carrying out the present invention,

there is provided a base bar 1 to which the lower ends of posts 2 areconnected. The base bar has been shown as being mounted in a pit 3 inthe ground, but it is not necessary that a pit be used. If, however, apit is employed, thenthe dirt may be prevented from sliding inwardly bymeans of side boards 4 extended between the posts 2 and shown in Fig. 1,the side boards being omitted in the other figures.

Each post comprises an outer member 5 and sides 6, these parts definingupright guides 7 in the posts 2.

r Transverse sills 8 are mounted in the ground on opposite sides of theposts 2 and are supplied with depressed seats 9 in which Ushaped pivotelements 10 are mounted,

- the pivot elements-receiving U-shaped straps 11 secured to the lowerends of upwardly 1nclined track rails 12 and 14, the track rails 12being united by a transverse tie strap 15 and the track rails 14 beingsimilarly connected. The track rails 12 and 14 are supplied at theirouter sides with guards 16, so that a vehicle moving along the railswill not be likely to run sidewise 0d the rails.

A gate 17 of any desired form is mounted to reciprocate vertically inthe guides 7 of the posts 2. On the upper edge of the gate 17, near tothe ends thereof, U-shaped hangers 18 are mounted, and through thehangers, a rod 19 passes, the rod having eyes 20 at its ends, the eyesbeing united with the lower ends of retractile springs 21, the upperends of which are mounted on pins 22. The sides 6 of the posts 2 areprovided with a plurality, of openings 23 in which pins 22 may bemounted to. adjust the tension of the springs 21. There may be anynumber of these holes 23.

U-shaped saddles or retainers 24 are mounted on the upper. edge of thegate 17 and carry pins 25. Below the pins 25 rollers 28 are journaled onthe retainers 24. The upper ends of certain of the rails 12 and 14 carryloops 26 engaged slidably around the pins 25. The upper ends of theother track rails 12 and 14 carry fingers 27, slidable beneath the loopsand supported onthe rollers 28, the loops 26 and the fingers 27 beingcurved vertically, .as shown in Fig. 1, so that these parts may coactproperly with each other when they .move downwardly along with the gate17, under the weight of a vehicle. It is to be noted that the rod 19 towhich the springs 21 are attached, passes through the'saddles orretainers 24, so that- 21 being put under tension, it being possibleforjthe automobile to move readily across the upper edge of the gate,from one side thereof to'the other when the gate is depressed asaforesaid. As soon as the automobilerides off the track rails 12 or 14,the s rings 21 will reassert themselves, raising the gate 17 anddisposing the track rails 12 and 14 in the inclined positions of Fig. 1.When the transversely of the pins 25, and the fingers 27 on the rails12'14 advance transversely of the rollers 28, the fingers beingsupported on the rollers.

Having thus described the invention, what I is claimed is: v

- 1. In 7 a device of the class described, guides; a gate slidable inthe guides; a retainer carried by the gate and comprising upstandingportions; a rod mounted in the upstanding portions of the retainer; anantifriction device on the rod between the upstanding portions of theretainer; inclined tracks having their upper ends slidably receivedbetween the upstanding portions of the retainer, the uppler end of. onetrack being supported on t e anti-friction device;

gate 17 is depressed as aforesaid, the loops 26 on the rails 1214advance means for pivotally mounting the lower ends of the tracks; andsprings each attached-at one end to the rod, the other ends ofthesprings being secured to the guides.

. 2. In' a device of the class described, A

track, the fii'iger being slidably received in,

the retainer, beneath theloop and the trans- .verse' element.

In. testimony that I claim the foregoing have hereto afiixed mysignature in the presenceof two witnesses.

as my own, I
